They are using a new method for suction doing away with the vacum tank all together,this works on the same princible like when you blow over a plastic straw which then causes a vacum.
We had this fitted on the machine and what a racket it makes ,the hiss of air loudly all day long ,and the compressor couldn't keep up with the air this method uses.So the boss told me to take it back off and fit the vacum tank back up again.
If you have a compressor just for the cnc then may be it would work (more expence said the boss)but the god allfull noise ,if you can think about 6 or seven air guns all going off at once ''the racket.''
Oh and your suction cup number is limited to about 5 or 6 because of the extra air pipes this system takes up ,i think thats right from memory ,i now it was right on the limit using the 160 Dia cups we had .
Thanks for the info stoned11 keep in touch
